我有5个Spinners。为了对此进行总结。
这是xml中的Spinner
<Spinner
android:id="@+id/text_interested"
android:layout_span="2"
android:layout_width="wrap_content"
android:layout_height="60px"
android:entries="@array/interestedarrays"
android:prompt="@string/interestedprompt" />
这是Java中的Spinner
submitbtn.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
interested.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
public void onItemSelected(
AdapterView<?> adapterView, View view,
int i, long l) {
interesting = interested.getItemAtPosition(i).toString();
}
public void onNothingSelected(
AdapterView<?> adapterView) {
}
});
}
});
这里的解释：
页面上有一个按钮。按下此按钮将从微调器读取数据。我用这个
检查了输出System.out.println(interested.getItemAtPosition(i).toString());
它甚至没有给我任何东西。
如何检索值并将其串起来？

试试这个：
String text = mySpinner.getSelectedItem().toString();
像这样，你可以获得不同的Spinners的价值。
答案 1 :(得分：20)
String Text = mySpinner.getSelectedItem().toString();
或
mySpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
Object item = parent.getItemAtPosition(position);
}
public void onNothingSelected(AdapterView<?> parent) {
}
});
答案 2 :(得分：9)
您可以使用
从Spinner获取所选项目interested.getSelectedItem().toString();
答案 3 :(得分：5)
试试这个
final Spinner cardStatusSpinner1 = (Spinner) findViewById(R.id.text_interested);
String cardStatusString;
cardStatusSpinner1.setOnItemSelectedListener(new OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parent,
View view, int pos, long id) {
cardStatusString = parent.getItemAtPosition(pos).toString();
}
@Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});
final Button saveBtn = (Button) findViewById(R.id.save_button);
saveBtn .setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
System.out.println("Selected cardStatusString : " + cardStatusString ); //this will print the result
}
});

如果您的Spinner由SQLite游标填充，那么解决方案是：
Spinner mySpin = (Spinner) findViewById(R.id.myspin);
mySpin.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
SQLiteCursor item = (SQLiteCursor) parent.getItemAtPosition(position);
String value = String.valueOf(item.getString(0));
Toast.makeText(getApplicationContext(), "The option is:" + value , Toast.LENGTH_SHORT).show();
}
PS：item.getString(0) - ＆gt; 0是您要获取的光标列的索引。

除了建议，
public class LifeCycleActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Toast.makeText(LifeCycleActivity.this,"ON CREATE", Toast.LENGTH_SHORT).show();
}
@Override
protected void onStart() {
// TODO Auto-generated method stub
super.onStart();
Toast.makeText(LifeCycleActivity.this,"ON START", Toast.LENGTH_SHORT).show();
}
@Override
protected void onResume() {
// TODO Auto-generated method stub
super.onResume();
Toast.makeText(LifeCycleActivity.this,"ON RESUME", Toast.LENGTH_SHORT).show();
}
@Override
protected void onPause() {
// TODO Auto-generated method stub
super.onPause();
Toast.makeText(LifeCycleActivity.this,"ON PAUSE", Toast.LENGTH_SHORT).show();
}
@Override
protected void onRestart() {
// TODO Auto-generated method stub
super.onRestart();
Toast.makeText(LifeCycleActivity.this,"ON RESTART", Toast.LENGTH_SHORT).show();
}
@Override
protected void onStop() {
// TODO Auto-generated method stub
super.onStop();
Toast.makeText(LifeCycleActivity.this,"ON STOP", Toast.LENGTH_SHORT).show();
}
@Override
protected void onDestroy() {
// TODO Auto-generated method stub
super.onDestroy();
Toast.makeText(LifeCycleActivity.this,"ON DESTROY", Toast.LENGTH_SHORT).show();
}
}
你可以，
String Text = mySpinner.getSelectedItem().toString();

当您从微调器中选择任何值时，您将获得选定的值
interested.getSelectedItem().toString();
答案 8 :(得分：2)
使用Kotlin获取所选项目：
<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:b="urn:swift:xsd:setr.010.001.03" exclude-result-prefixes="b">
<xsl:output method="xml" omit-xml-declaration="yes"/>
<xsl:template match="/">
<data>
<messageDataApps>
<field>
<fieldName>SENDER.STP</fieldName>
<value>
<xsl:value-of select="b:WBIFNMsg/b:AppMsg/b:Document/b:SbcptOrdrV03/b:MsgId/b:id"/>
</value>
</field>
</messageDataApps>
</data>
</xsl:template>
</xsl:stylesheet>

由于Android开发的最新语言是Kotlin。这是我们如何使用Anonymous对象在Kotlin中完成它。
spinnerName?.onItemSelectedListener = object : AdapterView.OnItemSelectedListener{
override fun onNothingSelected(parent: AdapterView<*>?) {
println("Nothing Selected")
}
override fun onItemSelected(parent: AdapterView<*>?, view: View?, position: Int, id: Long) {
val selectedString = yourList[position]
}
}

spinnerType = (AppCompatSpinner) findViewById(R.id.account_type);
spinnerType.setPrompt("Select Type");
spinnerType.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
TypeItem clickedItem = (TypeItem) parent.getItemAtPosition(position);
String TypeName = clickedItem.getTypeName();
Toast.makeText(AddAccount.this, TypeName + " selected", Toast.LENGTH_SHORT).show();
}
@Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
